FBI officials announced Tuesday that its offering up to $1,000,000 for information leading to the location of Robert A. Levinson, a 28-year Department of Justice employee who disappeared in Iran on March 9, 2007.

Levinson, 64, had arrived in Kish Island, Iran just one day before he went missing. It has been a year since the government received indications that he was being held captive by a group in southwest Asia, which includes border regions of Afghanistan, Iran and Pakistan.

In a video posted by the FBI in Feburary of last year, Levinson is seen speaking to his family and the government, saying that he's not in very good health, but that he is being treated well.

"We are committed to bringing Bob home safely to his family," James McJunkin, the Assistant Director in Charge of the FBI's Washington Field Office, said. "We hope that this reward will encourage anyone with information about Bob or his captors, no matter how insignificant it seems, to contact the FBI."

The FBI is also starting a billboard, radio and flier campaign advertising the reward and encouraging those with information to contact them.
